Ask mesh-delivery whether a merge's group still assembles (hq issue 525)

Browse Source 
A merge from any head waited for the window because the controller could not
see a group's members, so the window skip changed nothing in production and
unrelated merges walked one after another. The controller now asks
mesh-delivery's groups, within 3 s and before the plans are held: a merge
waits only when its head's group has another member whose pull request is
open and whose merge it does not keep yet (ADR 0306 §2). No answer means it
waits, and its batch says why. A headed merge in no waiting group and related
to no batch is cut at once, as one from no head is (ADR 0304 §1, ADR 0306 §3).

The controller's grant names mesh-delivery.groups. The installer's first user
list in mesh-host must carry it too before the genesis test can pass.
